基于alpine用dockerfile创建的nginx镜像

1、下载alpine镜像

[root@docker43 ~]# docker pull alpine
Using default tag: latest
Trying to pull repository docker.io/library/alpine ...
latest: Pulling from docker.io/library/alpine
4fe2ade4980c: Pull complete
Digest: sha256:621c2f39f8133acb8e64023a94dbdf0d5ca81896102b9e57c0dc184cadaf5528
Status: Downloaded newer image for docker.io/alpine:latest
[root@docker43 ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
docker.io/alpine    latest              196d12cf6ab1        3 weeks ago         4.41 MB

2、编写dockerfile(一)

2.1.创建存放文件目录

[root@docker43 ~]# cd /opt/
[root@docker43 opt]# mkdir alpine_nginx && cd alpine_nginx && touch Dockerfile && touch nginx.conf && touch nginx.vh.default.conf
[root@docker43 alpine_nginx]# ll
总用量 16
-rw-r--r-- 1 root root 5652 10月  4 18:15 Dockerfile
-rw-r--r-- 1 root root  638 10月  4 15:23 nginx.conf
-rw-r--r-- 1 root root  472 10月  4 15:24 nginx.vh.default.conf

2.2. 准备nginx.conf文件

[root@docker43 alpine_nginx]# cat nginx.conf 
user  nginx;
worker_processes  1;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
events {
    worker_connections  10240;
}
http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

2.3.准备nginx.vh.default.conf文件

[root@docker43 alpine_nginx]# cat nginx.vh.default.conf 
server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

2.4.dockerfile文件

# 将目录下的文件copy到镜像中

COPY nginx.vh.default.conf /etc/nginx/conf.d/default.conf

# 开放80端口
EXPOSE 80

STOPSIGNAL SIGTERM

# 启动nginx命令
CMD ["nginx", "-g", "daemon off;"]

2.5.创建镜像

[root@docker43 alpine_nginx]# docker build -t alpine:nginx .

2.6.创建容器

# 不进行宿主配置文件日志文件挂载
docker run -tid --name zjznginx  -p 80:80 -m 2048m  --memory-swap=2048m  --cpu-shares=256 alpine:nginx

# 挂载配置文件和日志
docker run -tid --name zjznginx  -p 80:80 -v /opt/Webs/nginx/nginx.conf:/etc/nginx/nginx.conf -v /opt/Webs/nginx/logs/:/var/log/nginx -m 2048m  --memory-swap=2048m  --cpu-shares=256 alpine:nginx

 查看容器

[root@docker43 alpine_nginx]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                NAMES

3、编写dockerfile(二)

3.1.创建存放文件目录

[root@docker43 ~]# cd /opt/
[root@docker43 opt]# mkdir alpine_nginx && cd alpine_nginx && touch Dockerfile && touch nginx.conf && touch nginx.vh.default.conf
[root@docker43 alpine_nginx]# ll

-rw-r--r-- 1 root root  472 10月  4 15:24 nginx.vh.default.conf

3.2.准备nginx.conf文件

[root@docker43 alpine_nginx]# cat nginx.conf 
user  nginx;
worker_processes  1;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

3.3. 准备nginx.vh.default.conf文件

[root@docker43 alpine_nginx]# cat nginx.vh.default.conf 
server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

PS：因为用的是脚本命令的方式启动的，没有守护进程 ，最后使用bash或者sh进入容器启动然后ctrl+p ctrl+q 退出

具体的解释：docker运行nginx为什么要使用 daemon off

启动nginx

[root@docker43 alpine_nginx]# docker run -ti --restart=always --name zjznginx  -p 80:80 -m 2048m  --memory-swap=2048m  --cpu-shares=256 alpine:nginx bash

查看容器

4、测试
